The game is set in the "not-too-distant future," according to its website. It's a world where humans battle machines for what few natural resources remain, and fight to "recharge" the globe with renewable energy.

Linkin Park dove into the clean energy movement in 2005 when they founded Music For Relief, a charity that provides help to people affected by natural disasters and supports clean energy projects. That charity's main movement currently is Power the World, a project it says is dedicated to raising awareness about the 1.3 billion people worldwide who live without electricity.

Dave Farrell, Linkin Park's bassist, hopes to address that problem by engaging his band's over 56 million Facebook fans.

"We're big believers in powers in numbers," Farrell said on stage at the Social Good Summit while talking to Mashable CEO Pete Cashmore. Farrell says Linkin Park's fans want to be active and aware of what's happening in the world around them, and so the band wanted to think of a way to direct that energy toward something positive.

"What better way than gaming?" Farrell said. "We grew up playing video games, and those games had all different types of messages."

He hopes that people who download the game on Facebook will team up and fight the resource-hoarding machines together, which is similar to how he hopes the game's message will spread. By playing something whose message is that the world needs clean energy to survive, he hopes awareness will spread and people will act.

"I say it all the time, the easiest thing that people can do — it doesn't take money, it doesn't take anything like that — is to be aware of what's going on, find out the information, and share it with your friends," Farrell said.
